Mawi DNA Technologies has developed iSWAB-DNA and iSWAB-RNA for collection and stabilization of mammalian cell nucleic acids.
iSWAB-DNA contains a proprietary lytic buffer that gently lyses mammalian cells over a period of 12+ hours resulting in long-fragment (>40kb), double stranded DNA ideal for any downstream application including NGS and Microarrays.
iSWAB-RNA works through a different mechanism, by stabilizing collected mammalian cells intact at room temperature. To collect samples, we recommend the use of cytobrushes on the same location of the cheek in order to access deeper basal layers. This process enables the collection of more viable cells and increases the quality and quantity of RNA.
